  1. TLS1.3 in Node.jsThis post details the technical work involved in integrating TLS 1.3 support into Node.js. It explains the prerequisite of updating to OpenSSL 1.1.1, the protocol-level differences between TLS 1.3 and TLS 1.2 that required specific handling in Node.js (handshake, session tickets, event timing, packet order), and the benefits of TLS 1.3 including assured forward secrecy, removal of RSA key agreement, safer cipher options (AES256, AES128, CHACHA20), and AEAD cipher modes.
